Be'vit known that I, -HENRY U NZ, a citizen of the United States,residing at Philadelphia, county of -;Phjladelphia,- andStat-e ofPennsylvania, have invented a new and use.- ful Improvement inRibbonSpools for Type- Writing Machines, of which the following is.

a full, clear, and exact description, reference being had to theaccompanying drawings,

which form a part of. this specification. *In the type-writer the typestrikes at a certain point on th eplaten, and therefore strikes i alwaysat a certain point in the inking-ribbon.

As ordinarily constructed, therefore, if the inking-ribbon be of somewidth, pnly a certain portion of it is useful in .type-writing,"and whenit becomes worn orthe ink' exhausted it requires a new ribbon.

My invention has for its object an improved construction whereby theribbon spools carrying the inking-ribbon may be given a lateralmovement, so that different portions of the inking-ribbon may bepresented to the action of the type, and as one portion of the ribbonbecomes worn the rib? bon may be shifted, so as to present a differentportion of the inking-ribbon to the action of the type, and thusthewhole width of the ribbon may be used in the operation oftypewriting. l p

In the drawings, Figure 1-:is a perspective side view of ribbon-spool,driving ratchetwheel, and ribbon-spool supports. Fig. 2 is a detachedperspective View of ribbon-spool,"

shaft,'and. ratchet-wheel with spool in its most shifted position. Fig.3 is a detached perspective view of'same, showing spool in anintermediate shifted position. Fig; 4 i's'a detached perspective view ofsame, showing on the shaft. Fig. 5. Fig. 7 is an end view ofribbon-spool.

and retaining-spring for retaining the spool Fig. dis a sectional viewof A is the ribbon-spool shaft, supported be,- tween the fixed bearing aand the spring-arm 01., Upon this shaft isthe ratchet-wheel 13,

0' is a-spring secured upon'the shaft, as

shown in'Figs. 5 and 6, D is the ribbon-spool, which is slipped overt-heshaft and held so wh eel are the steps or projecting surfaces old. Thespool is normally in such a position that the projecting pin 1) restsagainst the surface of the head of the ribbon-spook v E is the ribboncarried by the ribbon-spools. When for any reason it is desired to shiftthe ribbon-spool and the ribbon, the ribbon-spool is shifted and turnedupon the shaft until the pin b rests against'either of the projections dor (1, according to the extentof shift desired, by-which it isretained." By this means I am enabled to so shift the ribbon-spool thatI can cause the type to act upon different parts of side of' themachine.

as to rotate with it by means of' the spring C, 1 pressing against thesurface of said spool. Upon the end of this spool toward theratchet-Having nowfullydescribe'd my invention,

what I claim, and'desire to protect by Letters Patent, is

1. As a new article of manufacture, aribhon-spool provided with a stepor projection adapted to coact with a fixed stop on the machine forlocating the position of the ribbon on the spool with reference to thepoint of im pact of thetype; 2'. As a new article of, manufacture, aribbon-spool provided with two or more steps or fixed step orprojectionon the machine to locate theposition of the ribbon withreference to the printing-point of the type and to vary the position ofthe ribbon with reference to said printing-point.-

' 8. Ina type-writing machine, in combination, aribbon-spool providedwith a step or projection at its'head, and a stop upon the projectionsat its head, said 'stepsliprojecting -difierent extents andadaptedto-coactwith a v machine adapted to rest upon the step orprojection to locate the position of the ribbon with reference to theprintingpoint of the type and tovary the position of the ribbonwithvreferenee to said printing-point.

4. In a type-writing machine, in combination, a ribbon-spool, providedwith two or more projections or steps at its head, said steps projectingdifferent extents, and a stop upon the machine adapted to rest againstthe steps upon the ribbon-spool.

5. In combination, a ribbon-spool shaft, a disk upon said shaft, a pinprojecting from said disk, at ribbon-spool upon said shaft, and aprojection or step upon the head of said spool, adjacent to the saiddis:

6. In combination, a ribbon-spool shaft, a disk upon said shaft, a pinprojecting from said disk, at ribbon-spool upon said shaft, and two ormore projections or steps uponthe head of said spool, adjacent to thesaid disk, said steps projecting different extents from the body of thehead.

7. In combination, a ribbon-spool shaft, a driving ratchet-wheel uponsaid shaft, a projection from said ratchetwheel, a ribbonspool upon saidshaft anda projection or step upon the head of said spool adjacent tothe said ratchet-Wheel.

81 In combination, a ribbon-spool shaft, a driving ratchet-wheel uponsaid shaft, a pin projecting from said ratchet-wheel, a ribbonspool uponsaid shaft, and projections or steps upon the head of said spooladjacent to the said ratchet-wheel.

In testimony of which invention I have hereunto set my hand.
